SEECIZEIGATION forming part of-Letters Patent No. 449,099, dated March31, 1891.

Application filed September 30, 1890. Serial llo. 366,642- (No model.)

To all whom it may concern:

Be it known that I, ERNESTO ABBIATI, a resident of the city of NewYork,-in the county and State of New York, have invented a Clothes-LineFastener, 01": which the following is a specification. t

- My improvementrelates to an automatic locking device or clamp to beused in connec;

tion with a runningclothes-iifie'or ofhenline.

My object is to provide a simple device whereby the tension in a runningclothesline-niay be instantly increased or diminished, and that willautomatically lock itself. These objects lrattain by means of themechanism illustrated by the accompanying drawings, and hereinafterdescribed, wherei 11- Figure l is a sideview of the locking device orclamp as applied toa running clothesline. Fig. 2 is an enlarged sideview of the clamp, partly in, settion. Fig. 3- is a plan view of theclamp. fig. 4 is a cross-section of the-frame on the section-line c c,Fig. 3.

A is ihe slotted body or frame, constructed to allot/titheintroductionof the pulley B and the eccentric 1), Which is provided Withgt roundedface, which face has several transverse grooves, or' is otherwiseroughened, so that it will present a rong. contact-sniace. The pulleyand "eccentric are both heldin "place so as to be free to turn by meansof pins or gudgeons.

,. E is a handle or pin extending from the eccentric l).

G is a loop of wire or rope attached to the end of the body or'trame A.

in using this device-one end of the clothesline H is secured to theeccentric D, as indi- .oated The line H is then laid over pulleys M N,that are carried by stationary supports, and is finally carried over thegillley B between the same and the eccentric D, as shown in Figs. 1 and2. The loop G may carry an eye F, through which the rope ll is passed,but with such freedom as to allow rope H to slide easily. This eye Fholds the frame in apositioniparnllel'tothe rope ll,

' which insures quicker action of the eccentric D. As the tension on therope ll increases, its tendency will be to draw theeccentric 1) aroundin the direction indicated by arrow 1 until, as the radius of the camincreases, the rope will become jammed and held between the {ace of theeccentric and the pulley B.

By means oft-he handle r) the cam can be thrown back, thus disengagingthe rope,w hereupon the desired tension can be made, the handle Ereleased, and the cam D again automatically thrown against thc'rope tobind the same.

I do not desire to limit myself: to fastening the rope ll to theeccentric .l) by threading through a hole in eccentric, for it may befast cued to a screw-eye in said eccentric; but the said rope shouldconnectwith the eccentric to move the same into the binding position.

Having described my invention, what I claim is- The COll'lblllttlOil ofthe frame A, having loopG, with the pullcyli, eccentric D. and rope H,which is secured tosaid eccentric, said
